Used in the UK as a slang word for funny, its unsure where the word started being used in this way but its one piece of slang that has swept its way across and is now used by most people in GB its due to the fact that something makes you laugh so much that your leaning over and cause your sides to "crease" tho its now used very over-commonly.
